Idk how you would get a list of every wiki, but i way i can think of to find a bunch of random wikis would be searching a very basic term like “the” or “and” on any wiki and then setting it to show all wikis (note i haven’t actually tried this lol. but i have done it with more specific stuff like character names)

@NoPartyThisTime Thank you for assisting reply.

To me, I would use the Google search engine, to search for random pages on random wikis. But in FANDOM, since there are so many of them, finding it would be a challenging task. So, searching in the bar using all wikis option, would be the best.
